I don't but my level is can the actor pass as the character. I have never given rats ass what race, culture, sex, age or any other real world features they have, just can they pass as what the character supposed to be.
The Endless don't have set in stone features, but they do have looks. Mostly becouse the changing artists but also because it plays into their otherworldlyness. With Death that look happens to be a pale goth girl in her early twenties. An asian actress can look like that but a black actress can't. I would prefer if they hired a white actress on the role as that what Death mostly looks like but any pale POC would have been fine too.
